Tetra-Repeat Microsatellite Markers for the Masu Salmon (Oncorhynchus masou masou) and Its Application in Cross-Subspecies Amplification
نویسندگان
چکیده
We developed tetranucleotide-repeat microsatellite markers for the masu salmon (Oncorhynchus masou) complex. 454 pyrosequencing was used to discover repeat motifs, and seven polymorphic microsatellite-primer sets were identified. The number of alleles detected at each locus ranged from four to 24 and the expected heterozygosity varied from 0.57 to 0.92. Cross-subspecies amplification for O. m. masou, O. m. ishikawae and O. m. subsp. was successful. These microsatellites can be utilized in studies of genetic structure, genetic diversity, and intra- and inter-subspecific hybridization, making a contribution to conservation and management of the Oncorhynchus masou complex.

Genetic diversity and differentiation of masu salmon (Oncorhynchus masou masou) between and within cultured populations inferred from microsatellite DNA analysis.
Masu salmon, Oncorhynchus masou masou, is one of the most valuable fishery species that has been introduced to China, though to date no studies on the genetic diversity and genetic relationship among hatchery populations has been performed with molecular markers. We undertook such a study and sampled 120 individuals from three hatchery stocks and analyzed 20 microsatellite loci. All loci were p...

The population genetic structure and phylogeography of masu salmon were investigated by using variation in the mitochondrial NADH dehydrogenase subunit 5 gene (ND5) and six polymorphic microsatellite loci among a total of 895 fish representing 18 populations collected from Japan (9), Russia (7), and Korea (2) from 2000 to 2008. An analysis of ND5 nucleotide sequences revealed 22 variable sites ...

Although the difference in allergenicity between landlocked and anadromous salmon is little understood, only anadromous salmon are recommended to be labeled in the current allergen labeling system. This study was designed to examine the allergenic potency of landlocked species (yamame) and anadromous species (sakuramasu) of masu salmon Oncorhynchus masou masou, with special reference to parvalb...
متن کاملCharacterization of DNA polymerase induced by salmon herpesvirus, Oncorhynchus masou virus.
A DNA polymerase induced by Oncorhynchus masou virus (OMV) was isolated from cultured salmon cells infected with OMV using sequential ion-exchange column chromatography steps. The properties of the OMV polymerase were compared to those of human cytomegalovirus (HCMV) polymerase and polymerase alpha from cherry salmon (masu salmon, O. masou) testes. OMV polymerase was clearly distinguished from ...

Most of the non-migratory forms will live continuously in their natal rivers throughout their lives (Fig. 1). Regardless of these life history types, most salmonids will spawn in freshwater environments, mainly in their natal rivers (Fig. 1) (Quinn 2005). From these phenomena, salmonids are consid...
